The problem with this approach is that you'd have to modify EVERY
disk controller, not just the SCSI card, in order to make HFS bootable.

On the other hand, DOS FAT does not hog up block 0 so it is
possible to get GS/OS booting off it without any hardware
modification.

It seems to be that the formula for >32MB plus bootability=DOS FAT

Would ISO9660 be another possibility?  Bootability without
hardware mod, that is.

Besides, VFAT could be used for long file names.
